Abstract

Procedimiento para el tratamiento de ácidos grasos naturales que comprende calefacción, adición de disolución de peróxido de hidrógeno y destilación. Procedimiento para el tratamiento de ácidos grasos naturales que comprende calefacción hasta 150-230ºC, adición de 3-50% de una disolución de peróxido de hidrógeno durante al menos 10 minutos a la temperatura de reacción y destilación para que los ácidos grasos que contienen cromóforos se convierten en material de alto peso molecular que permanece después de la destilación.Process for the treatment of natural fatty acids comprising heating, addition of hydrogen peroxide solution and distillation. Process for the treatment of natural fatty acids comprising heating up to 150-230 ° C, addition of 3-50% of a solution of hydrogen peroxide for at least 10 minutes at the reaction temperature and distillation so that the fatty acids containing chromophores are they become a high molecular weight material that remains after distillation.
